    unfortunately the efs partition does not contain everything you need to backup your nv. this is geared more towards GSM devices where wiping out your EFS would result in the phone no longer being a useful phone but instead a shiny "ipod touch". as you can see in teh screenshot it has the phone gt-s5830i which is the samsung galaxy ace. it was a gsm samsung device that was later made into a cdma variant several months later as the prevail, and then finally as the samsung admire on metropcs. that should give ya an idea on how old this tool is :)


    "In an initial attempt to solve this problem, users have attempted to "dd", or create an image of, a single block supposedly containing the IMEI when the phone is still in a good state. This is the efs.sbn method that you may have seen. However, upon further inspection, it turns out the IMEI data is actually spread across five different block devices, hence why the efs.sbn method is either ineffective or leaves you on roaming!"

    just incase anyone was wondering the source of my info http://forum.xda-developers.com/showthread.php?t=1852255
